Examines university employees' (N=130) awareness and perceptions of the importance of university counseling and consultation services. Results indicate that employees fell into 1 of 4 groups sharing similar perceptions of counseling and consultation activities. Implications for service provision and research are discussed.

The valid provision of subscores from an item response theory-based test implies a multidimensional test structure. Assuming, in the construction of a new test, that the test features required for a valid and reliable total test score have been specified already, this article describes the resulting subscore performance and the resulting…

Prior to a three-way component analysis of a three-way data set, it is customary to preprocess the data by centering and/or rescaling them. Harshman and Lundy (1984) considered that three-way data actually consist of a three-way model part, which in fact pertains to ratio scale measurements, as well as additive "offset" terms that turn the ratio…

Observers made speeded old-new recognition judgments of color stimuli embedded in a multidimensional similarity space. The paradigm used multiple lists but with the underlying similarity structures repeated across lists, to allow for quantitative modeling of the data at the individual-participant and individual-item levels. Correct rejection…

Many statistical models have been used to study human development. The multidimensional scaling (MDS) method has been an under-utilised technique in psychological and educational research for studying such phenomena. In this paper, MDS profile analysis was used to examine adolescent mood change patterns over a 1-week period. This method is used to…

Most researchers agree that psychological/educational tests are sensitive to multiple traits, implying the need for a multidimensional item response theory (MIRT). One limitation of applying a MIRT in practice is the difficulty in establishing equivalent scales of multiple traits. In this study, a new MIRT linking method was proposed and evaluated…

Wellbeing is a well-used but ill-defined term in youth research. This paper describes research that explored the ways in which young people and youth workers define wellbeing. The findings suggest that both groups agreed that wellbeing was a multidimensional concept; however, the young people were more likely to consider wellbeing to be influenced…

This study examines how mathematics and science teachers' classroom assessment practices were affected by the National Board Certification process. Using a 3-year, longitudinal, comparison group design, evidence of changes in teachers' classroom practice were measured on six dimensions of formative assessment. The National Board candidates began…

Holland's (1973) theory of vocational choice proposes a typology of, and a match between, people and occupations. The Self Directed Search (SDS) can be used to assess people's occupational orientation types. To assess the construct validity of Holland's theory of occupational preferences, 171 female industrial workers participated in a study,…

The perceived similarity of Holland's vocational personality stereotypes was examined using the techniques of nonmetric multidimensional scaling. Three job titles (JTs) were selected for each of Holland's stereotypes. These 18 JTs were then randomly paired. The resulting 153 pairs comprised an inventory which was administered to all students in a…

A maximum likelihood estimation procedure is developed for the simple and the weighted additive models. The data are assumed to be taken by either one of the following methods: (1) categorical ratings--the subject is asked to rate a set of stimuli with respect to an attribute of the stimuli on rating scales with a relatively few observation…

An hypothesis concerning a definition of the concepts assimilation and accommodation was tested. Both assimilation and accommodation were hypothesized to be processes that produce changes in cognitive structures--internal representations used to organize behavior. The hypothesis is that, in contrast to assimilation, the changes in structure caused…

This report describes a test of the robustness of factor-analytic methods in the face of various types of scale transformations on the data. Because of the complexities that would be involved in an exact analytical investigation, the tests were done with simulated sets of data having different factor structures. After factor analyzing the original…

The Cartesian theory of dimensionality (defined in terms of geometric distances between points in the test space) and Leibnitzian theory (defined in terms of order-generative connected, transitive, and asymmetric relations) are contrasted in terms of the difference between a factor analysis and an order analysis of the same data.
